Vinca minor '24 Karat' PP#20,289
Lovely blue blooms in late spring and early summer on this evergreen groundcover.
Plant Patent #20,289. At last, a new look for Periwinkle! '24 Karat' is an absolutely stunning new cultivar with leaves that open bright yellow-gold and keep their color for weeks. They continue to open throughout the growing season, so there is a lovely play of yellow and green on this easy-to-grow groundcover.
Evergreen and content either in full shade or partial shade, '24 Karat' sets masses of pale blue blooms in late spring and early summer, adding another color to the brilliant display. It is a densely set, compact plant that spreads (or trails) 12 to 15 inches wide but reaches only about 3½ inches high. Ideal in the front of the border, edging pathways, or accenting containers, it is a versatile and very robust performer.
Almost any green- or blue-leaved plant looks superb beside '24 Karat.' Use it in front of Digitalis, Penstemon, and Phlox, among many others. It makes a great foreground planting to ornamental grasses as well.
'24 Karat' was introduced by Itsaul Plants of Georgia, so you know the breeding is superb. You will find it very easy to grow, tolerant of heat, humidity, and cold, untroubled by most pests and diseases, and long-lasting. Cut it back in late winter to make way for fresh growth, or leave it alone and let the shining gold leaves emerge above the older growth. Foolproof and always lovely, it's a must-have. Zones 4-9.

- Butterflies like a lot of sunlight, so locate your garden in a sunny area.
- If you live in a windy location, plant your butterfly-attracting plants near a building, fence, or hedge to protect them.
- Plant a variety of nectar-rich plants, as well as shrubs and evergreens for shelter.
- Since many butterflies and native flowering plants have co-evolved, try to put in some that are native to your area. The Lady Bird Johnson Wildlife Center provides lists of plants native to states and regions.
- Certain colors are particularly attracting to butterflies – red, yellow, pink, purple, or orange blooms that are clustered or flat-topped, with a short flower tubes are especially attractive to adult butterflies.
- Avoid using pesticides, especially around nectar-producing plants.
- Provide a shallow source of water – try a birdbath with pebbles lining the bowl.
- Place a rock in a sunny spot for butterfly basking and resting.
- Create a "puddling area" by digging a shallow hole filled with compost or manure where rainwater will collect and release essential salts and minerals.
- If you want butterflies to breed in your garden, put in some caterpillar food plants, such as parsley, milkweeds, asters, thistles, violets, clover, grasses, and Queen Anne’s Lace.
- Since butterflies need nectar throughout the entire adult phase of their lives, try to create a design that will allow for a continuous bloom – when one stops blooming, another starts.
